What decision this helps you make: Whether an employer contributing to a multiemployer plan faces withdrawal liability, how large it could be, who else in the group is on the hook, and what has to happen before the assessment becomes final.

What this topic is

A multiemployer pension plan is a defined benefit plan maintained under collective bargaining agreements with more than one employer, typically in construction, trucking, grocery, or entertainment. When a contributing employer stops contributing — by exiting the business, losing the union contract, or simply shrinking — the Multiemployer Pension Plan Amendments Act of 1980 imposes withdrawal liability: the employer's allocable share of the plan's unfunded vested benefits, assessed by the plan and payable on a schedule.

Why it matters

The number can be enormous relative to the employer. A regional trucking company with $40M of revenue can face a withdrawal assessment of $60M or more, because the liability reflects a share of a plan's total underfunding rather than anything about the employer's own workforce. It does not appear on the balance sheet until it becomes probable and estimable. It is joint and several across the entire controlled group. And the statute requires the employer to start paying while it disputes the assessment.

Who should learn it

CFOs and general counsel at unionized employers, private equity and strategic acquirers doing diligence on a target with union plans, restructuring professionals, benefits counsel, and anyone valuing a business that appears in an ASC 715-80 disclosure.

What you will understand

  • What triggers a complete or partial withdrawal, and the industry exemptions that change the trigger
  • How the liability is allocated and capped, and why the twenty-year cap can make a large assessment survivable
  • Why controlled group liability makes this a group problem and a live private equity issue
  • The pay-first-dispute-later rule and the arbitration deadline that forfeits every defence if missed

Prerequisites

Common misconception

"We only have twelve employees in that plan, so the exposure is small." The allocation is not headcount-based in the way people assume. Under the presumptive method it reflects your share of contributions over a rolling period applied to the plan's change in unfunded vested benefits — and in a plan that is 45 percent funded with a shrinking contribution base, a small employer with a long contribution history can be allocated a share far out of proportion to its current workforce.
